Title
(EN) SELF-TUNING ZERO CURRENT DETECTION CIRCUIT
(FR) CIRCUIT DE DÉTECTION DE COURANT NUL À ACCORD AUTOMATIQUE
Abstract
(EN)
An apparatus is provided which comprises: a comparator circuitry (e.g., auto-zero comparator) to having a first input, a second input, a third input; and an output; a first device (e.g., a low-side switch) coupled to the first and second inputs of the comparator; and a circuitry (e.g., a self-tuning logic) to generate a digital code which represents a comparator offset adjustment with reference to detection of current through a second device (e.g., an inductor), wherein the digital code (e.g., a multibit digital signal) is provided to the third input of the comparator circuitry.
(FR)
L'invention concerne un appareil qui comprend : un circuit comparateur (par exemple, un comparateur à décalage automatique du zéro) ayant une première entrée, une deuxième entrée, une troisième entrée et une sortie ; un premier dispositif (par exemple, un interrupteur côté bas) couplé aux première et deuxième entrées du comparateur ; et un circuit (par exemple, une logique d'accord automatique) pour générer un code numérique qui représente un ajustement de décalage de comparateur en ce qui concerne la détection de courant dans un deuxième dispositif (par exemple, une bobine d'inductance), le code numérique (par exemple, un signal numérique multibits) étant fourni à la troisième entrée du circuit comparateur.
